The age of marriage should not be earlier than 22 for men and 20 for women. Marriage is invalid and not protected by law because it has not reached the legal age for marriage. The people's court shall not support an application for invalid marriage to the people's court on the grounds that the marriage is under the age of marriage and the legal invalid marriage situation has disappeared at the time of application.

Provisions on marriage:

1. Marriage should be completely voluntary by both men and women, and it is forbidden for either party to force the other, and no organization or individual can interfere.

2. The age of marriage should not be earlier than 22 for men and 20 for women.

3. No lineal blood relatives or collateral blood relatives within three generations.

4, monogamy, not bigamy.

5. After registered marriage, according to the agreement between men and women, the woman can become a member of the man's family, and the man can become a member of the woman's family.

6. Both men and women who want to get married should apply for marriage registration in person at the marriage registration office. Those who meet the requirements of this law shall be registered and issued a marriage certificate. The marriage relationship is established when the marriage registration is completed. Those who have not registered for marriage shall re-register. Marriage must reach the legal age for marriage. Before planning to get married, everyone must see if they and their partners meet the legal requirements.

Who can declare a marriage null and void?

1. Although the invalid marriage lacks legal elements, the parties to the marriage have gone through the marriage registration procedures, and the marriage registration has the legal effect of confirming the marriage relationship. Therefore, only legal institutions can declare a marriage relationship that lacks legal elements invalid.

2. In our country, the people's court is the institution that has the right to declare the marriage invalid, and no other unit (including the marriage registration office) or individual has the right to declare the marriage invalid. There are two situations in which the people's court declares a marriage invalid: the people's court declares a marriage invalid according to the application of the parties or interested parties, and makes a judgment to declare a marriage invalid according to law; In the process of hearing a divorce case, if the people's court finds that the marriage relationship between the parties is really invalid after examination, it will inform the parties that the marriage is invalid and make a judgment declaring the marriage invalid. When a people's court hears a case of annulment of marriage or divorce, mediation is not applicable to the trial of the validity of marriage, and it shall make a judgment according to law; Once the judgment on the validity of marriage is made, it will take legal effect.
